It would be useful to be able to add synonyms to ElasticSearch that may be specific to our industry, or may have been simply missed. For instance, currently if someone searches reimbursement, but an article only includes the term reimburse, the article does not come up. We also found missing synonyms for denied vs deny, testing vs test, refund vs reimburse (although fuzziness helps somewhat with different formats of the same word).
We also would like to be able to add industry specific synonyms and acronyms such as PDP for Prescription Drug Plan or Medigap plan for Supplemental plan.

I did some digging for you about using synonyms with ElasticSearch. According to the article here synonym search is not available in Paga's deployment of ElasticSearch. I have also reviewed documentation of Pega releases since that article was written and I do no see synonym support being released.
